Guy, I have some thoughts for you. If your 3/4 ton has a 6900# GVW now and
you add another 3/4 ton rear which has a 5000# rating your max. GVW will be
11,900# (I think). How much does the truck weigh with the car carrier body
and added axle? Subtract that from the 11,900# GVW and you will find out
how much load you will be able to carry. I don't think you will be able to
carry anything very heavy....maybe 3000-4000 max. ?
I think I would look for a larger truck!
My 2 cents!!!
